IMPROVEMENT IN MINING-PUMPS- The Schedule referred to in .these Letters Patent and making part of the same.e

To all whom 'it may concern t Be it known that `I HIRAM WOLF, of St. Louis, in the county of St. Louis, andState of Missouri, have invented a new and useful `Improvement in Fumps; and I do hereby declare'ithe following to be a full and correct description of the same, suiiicient to enable others skilled in the art to which my invention appertains, 4to fullyunderstand auduse the same, reference being had to the accompanying drawings, which make part of this specification, and in which i Figure l, SheetI; isfa front elevationv of my improvement in pumps;

Figure 2, Sheet 1I, is a central longitudinal vertical .section of one section of the same; and

i Figures and 4, Sheet II, are detached vertical sections of the suction and force-pumps.

Figure 5, Sheet III, uis a vfront view of a modificar tion of one of the pumps of my improvement.l Likeletters of reference indicate likefparts in the several iigures. r l l My invention being applicable to that class of pumps generally, which lift water, forany purpose, from great depths, commonly called five-story pumps, is more especially adapted for mining-purposes, when water has 4 ,to be lifted from a depth of several hundred feet; and

- It consists in the arrangement, above each other, of a series oi'sections, each section containing a reservoir and two pumps, the discharge-orifice of which pumps is on a level with or above the tops of the reservoir, so that the pumps, after receiving the water by suction, or, more properly speaking, by the weight ofthe atmosphere, has to force or lift it but the distance oi.I itsglength', as it flows from `the discharge-mince to th reservoir by its own .gravity thisdistance being but "one or Vtwo -feet, "relieves thepiston-rod from the immense weight,'which, in this classof pumps, hasf heretdfore .proven the great obstacle' to elevating' water riem great depths. VThese sections are complete in themselves, so that any number of them may be placed one above the other, till they reach the required height 'or depth,and.1nay be 'attached to each' 'othenin a simple and expeditious manner, the whole of the. pumps, attached to the several sections, being operated 4by Also, in pivoting the pumps of each section in such a manner that they can beeasily brought 'into a horizontal position, from a 'vertical one, ii', from any cause, it becomes necessary to reach the interior of any of them, and thus any repair can be made, without the necessity of detaching thepnmps from-.the frame.

Also, in connecting 'each pump with two reservoirs, one on the section nextbelow from which it receives the water by atmospheric pressure, `and vthe other inits own section, into'which itdelivers the water lifted from the reservoir-'next below. A

Also, in the peculiar construction of the pumps, as hereinafter more fully'described y In the drawings, I have shown but three sections, A, B, C, though' any required number'of them may be employed.

Each section consists of four uprights D, connected by cross-pieces E, the heads ofthe uprights being Yprovided witih sockets F, into which fit the lower ends of the uprights of the next section'above. These sections ought to be made of the same size, so that any number 'of them may be placed one above the other, Vwith the certainty ot' iitting. l

Attached to the cross-piece E, at opposite sides of the -frame of the sections, and 4separately secured to each section, are flat pieces G, the upper end of yeach being provided with a plate, H, (see iig, 2,)y 'to which the lower end of the piece G, next above, is "secured, thus forming a-continuous piece, which may be detached in sections at pleasure.

On these pieces G- are secured the pumps I, their discharge-orifice being level with, or above the top of the reservoir J of their own sections.

lhe reservoirs J may bemade of any suitable material, and in any suitable form,"and may be attached to their respective sections in any convenient manner.

- In-the drawings, I have shown the reservoirs pro` vided with a cover,through which pass the connecting-pipes K. L, the pipes K being attached to the suction-part of the pumps I, and leading to the reservoir nextvbelow, and the pipes L .being connected to the forcing-part of the pumps, and leading to the reservoir next above. 'I

vThe pumps consist of the pumps'proper I, (see figs. 3 and 4,) in which the piston i moves on the rod j.

Thelower. end of the pump is packed, as shown at o, which packingy is held in place by a screw-nut, 7c, f i through which packing and nut passes the pistn-rod, l

thus enabling me to connect the ends of the piston- -rods to each otherfdirectly and in a veltical line, so

that the power is exerted in a direct line on each piston-mod. i

In iig. `5,1 have shown a modification of the opera-- tion of the piston-rod, to-obviate the necessityof passing the same through the lower part of the pumps, so asto prevent any leakage.

The rod j is provided at each pumpl with an arbol,`

j* l to which the short piston-rod j" is attached.- This arbor encrcles the pump, and is of suii'cicnt size tovalve-chamber l:zy-*of the suction-palt, by means of thel .channel g.

The top ofthe valve-chamber isv closed by a screwbolt, f, the lower end of vwhich is hollow, to receive and guide the stem of the valve e.

The lower end of the valve-chamber forms a channel, d, connecting with the suction-pipe K, which is secured to the valve-chamber by a. screw-nut, c.

The valve-chamber l) of the force-pump connects with the lower end of the pump I, by means of the channel a, (fig. 4,) the valve 'm being arrangedin the same manner as the valve e, and bears such relation to the latter, that when the piston t' is moved upward the valve e opens, while the valve m is closed, and the water drawn by atmospheric pressure from the lower reservoir,.throngh pipe K, into the pump.

When the piston descends, the valve e is closed and valve lm opened, and the water forced up to the discharge-orifice, from which it ows, by its own gravity, through pipe L, into the reservoir of that section.-

rIhe pipes L are secured to the upper side of the valve-chamber b by screw-uut b. A

The piston-rods j are connected to each other, by means of the right and left-hand screw-nuts u.

'lhe pump proper I is, at its back, provided with a flange, O, which, again, has formed on it a cross-flange, P

The flange O is provided with a slot, in which plays loosely, a nut, R, into which one end of a screw, S, fastens, which latter passes through the piece G and flange l. l

rlhis screw S forms the pivot ou which the pump can be turned from a vertical to a horizontal position, when it is vnecessary to repair or clean it. To keep it in a vertical position, four screws, s, pass through the piece G into lange P.

I have shown the pump I attached to the outside of the frame of the sections, as I- am thereby enabled to more clearly show their operation. In actualuse, I propose to place the same on the inside of the frame,

thus saving space and also connecting-pipe, and having the pumps and all \\'o1-king.-apparatus protected by the frame.

M represents a walking-beam, pivoted ou standards N, secured to the standards of .the uppermost section, to the ends of which are connected the piston-rods of the pumps of section A.

Motion is imparted to the walking-beam in any suitable manner, and the piston-rods of the several pumps being connected to each other, all` the pumps are operated simultaneously, one side in the opposite direction of the other, so that a continuous flow into the reservoirs and suction from the same is kept up.

Each section is made of a height'of twenty-live feet, or less, so as to enable each pump to lift the water easily, without undue pressure of the atmosphere.

To facilitate thel movement of the piston-rod, and to relieve the strain of its weight from the point of attachment to the walking-beam, I attach a cord, 1), to the connections ofthe pistonrods, as shown at r, which cord passes over a' roller, q, attached to theV frame I) E, and has attached to it a weight, s', of suficient size to counterbalance the weight of that scc- 'the pistonrods.

tion of the piston-rod t'. vIn this manner, the point ot' attachment of the piston-rod to the walking-beam is relieved from the weight of the piston-rod.

The operation of my device is easily understood.

A sufficient number of sections having been connected to each other to reach the required depth, motion is given to the walking-beam, and through it to At each stroke, the pistons of one side descend, while the pistons of the other side ascend. The ascending pistons draw the water through pipes K from the well or the bottom of the mine and the several reservoirs, while the descending pistons force the same upwardly into the discharge, fromwhich the water ows, by its own gravity, into the reservoir. At the next stroke the two sides reverse their function. eiuX-pipe, J', through which the watenis discharged. In this manner a constant and steady stream of water is discharged.

If, in employing this pump in mines, the shaft in which it is used is sunk deeper, and it becomes necessary to lengthen the pumps, the top-section may be det-ached, and any suitable number of sections attached to the pumps, the top-section replaced, and the piston-rods, pipes, and reservoirs connected, when the operationof the pump can be continued.

This pump can be constructed very cheaply, and without much trouble, as the frame may be made out of rough timber, the ends being trimmed to fitinto the sockets F, which, when rough cast, willbe of very little expense.

The reservoirs may consist of open wooden tubs, and the pipes may be led into them in any suitable llfllinllel.

rlhe pumps can be cast very cheaply, and the expense vof my pumps will be very small compared with pumps now in use for similar' purposes.

Having thus described my invention,

What I claim as new, and desire tosecure by Letters Patent, is

l. The arrangement, above each other, of any desired number of sections, as herein described,' each section containing one reservoir and two pumps, the

discharge-orifices of which pumps are level with orl above the top-part of the reservoir, substantially as and for the purpose set forth.

2. vlhe pumps I, when pivot-ed in such a manner that they may be brought i'om a vertical to a horizontal position, substantially as and for the purposes 'set'fortl'n and pipes K and L, substantially as and for the pur-- poses set forth.
